Are pine trees and bamboo green?

"Pine and green bamboo" means: pine and green bamboo.

Pine refers to a firm ambition; Bamboo symbolizes a noble and upright spirit, keeps green all the year round, and belongs to a clean stream in nature; Because bamboo has high flexibility, it symbolizes the tenacity and longevity of life. Because its branches are bent rather than folded, it is a symbol of integrity and pride.

When the climate is not suitable (such as cold and dry), ordinary deciduous trees turn yellow and fall leaves in autumn and winter because of their large leaf area and no waxy film on the surface. And pine, holly, cypress and so on. Because the leaves are either tapering or have a layer of wax on the surface, the water is not easy to lose, so they can still survive normally in harsh environment, so they will not fall leaves and remain evergreen.
